Research Projects
Each year, IRDA's R&D Team conducts more than one hundred research projects in sustainable agriculture. What's more, IRDA is working with Quebec's key agricultural stakeholders to find concrete solutions.

Using seasonal tillage in combination with cover crops as a biological method to control cutworms in organic cruciferous crops
Evaluation of new practices to control cutworms in organic vegetable production.
Researchers: Annabelle Firlej Maxime Lefebvre
Developing mass trapping strategies to control the striped cucumber beetle in organic cucurbit farming
This project aims to develop mass trapping strategies to keep damage caused by the striped cucumber beetle populations below the economic threshold, while minimizing the capture of pollinators and natural enemies.
Researchers: Annabelle Firlej Maxime Lefebvre
Developing fertilization strategies for organic garlic farming that combine green and farmyard manure, while taking their N and P supply dynamics and soil quality impacts into account
By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.

Developing strategies and methods for weeding carrots grown in rotation with field crops
Development of weeding strategies and methods that will reduce weed pressure on carrot crops, especially row-crop carrots, which appear to be the most problematic.
Researcher: Élise Smedbol
Developing an organic farming protocol for young vegetable shoots: a multidisciplinary approach
This project will help lead to the development of an organic farming system to grow baby greens.
Researchers: Caroline Côté Annabelle Firlej Carl Boivin Maryse Leblanc
Evaluating a protocol for growing organic market garden cabbage using split band applications of granulated laying-hen droppings
This project aims to develop a GHD-based fertilizer management system using split band applications for high-N-demand crops grown in rows, e.g., summer cabbage.
Researcher: Christine Landry
Evaluating the effect of seeds coated with commercial, mycorrhizal fungi inoculum on the yields of nantes carrots grown in mineral soil early in the organic transition process
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
Researcher: Christine Landry
Multidisciplinary assessment of organic production systems for baby lettuce on muck soil
This project aims to assess the impact of cropping practices on baby lettuce yields and quality on muck soil.
Researchers: Caroline Côté Annabelle Firlej
Assessment of weed control products applied along the edge of plastic mulch in organic agriculture
A series of herbicides has been tested along the edge of the plastic mulch.
Researcher: Maryse Leblanc
Selection and management of legume intercrops in organic vegetable production
This project proposes ways of using legume intercrops to control vegetable pests (insects, diseases, and weeds) while increasing soil productivity and quality and economic yields.
Researcher: Annabelle Firlej
Biological control of leek moth through the release of trichogramma wasps in organic leek production in Québec
This project as aimed at comparing the efficacy of two parasites (T. brassicae and T. ostriniae) on leek moth.
Researcher: Annabelle Firlej
Control strategies for swede midge in organic production
This project evaluated effective and economically viable control strategies for swede midge that are healthy for both humans and the ecosystem.
Control of the striped cucumber beetle in organic cucurbit production
This project determined the efficacy of various pest control products on the striped cucumber beetle on organic cucurbit crops.
